We are developing a prototype X-ray detection system that should be ideal for many types of synchrotron science. X-rays are captured directly in thick, high-resistivity, single-crystal, silicon pixel sensors. Unlike other X-ray detectors, which have

3D processed silicon detectors offer several advantages over conventional, planar processed devices. The electric fields between the electrodes of a 3D detector are parallel to its surface, and for a given applied bias, stronger than those found in a
